5.2 Three-Dimensional Graphics with EZ Command
In the same way that ez functions are used to represent two-dimensional graphics without specifying the field of
existence of an array form, three-dimensional graphics of warped curves, surfaces, contour lines, contour and other
types of graphics can also be used, the commands to use are as follows:
ezcontour(f )
ezcontour(f, domain)
ezcontour(...,n)
Contour graph of f(x,y) in [-2p, 2p] x [-2p, 2p]
Contour graph of f(x,y) in the given domain
Contour graph of f(x,y) in mesh of size n x n
ezcontourf(f )
ezcontourf(f, domain)
ezcontourf(...,n)
Filling contour graph of f(x,y) in [-2p, 2p] x [-2p, 2p]
Filling contour graph of f(x, y) in the given domain
Contour graph of f(x, y) filling in a n x n mesh
ezmesh(f )
ezmesh(f,domain)
ezmesh(...,n)
ezmesh(x, y, z)
ezmesh(x, y, z, domain)
ezmesh(..., 'circ')
Filling mesh graph of f(x,y) at [-2p, 2p] x [-2p, 2p]
Filling mesh raph of f(x,y) in the given domain
Filling Mesh graph of f(x,y) in the nxn mesh
Mesh graph for x = x(t,u), y = y(t,u), z = z(t,u) where t,uŒ[-2p, 2p]
Mesh graph for x = x(t,u), y = y(t,u), z = z(t,u) where t,uΠdomain
Mesh graph of a circle, not the default square, centered in the domain
ezmeshc(f )
ezmeshc(f, domain)
ezmeshc(...,n)
ezmeshc(x, y, z)
ezmeshc(x, and z, domain)
ezmeshc(..., 'circ')
Performs a combination of mesh and contour graph elements
ezsurf(f )
ezsurf(f, domain)
ezsurf(...,n)
ezsurf(x, y, z)
ezsurf (x, y, z, domain)
ezsurf(..., 'circ')
These make a colored surface chart
ezsurfc(f )
ezsurfc(f, domain)
ezsurfc(...,n)
ezsurfc(x, y, z)
ezsurfc(x, y, z, domain)
ezsurfc(..., 'circ')
This creates diagrams that are a combination of surface and contour graphs
ezplot3(x, y, z)
ezplot3(x, y, z, domain)
ezplot3(..., 'animate')
Parametric curve in 3D for x = x(t), y = y(t), z = z(t) tŒ[-2p, 2p]
Parametric curve in 3D for x = x(t), y = y(t), z = z(t) tŒdomain
Parametric curve using 3D animation
ezpolar(f )
ezpolar(f, [a, b])
Graph the polar curve r = f(c) with cŒ[0, 2p]
Graph the polar curve r = f(c) with cŒ[a, b]
